nevi7 and useful Improvements in Fastenings.

for Safe or Vault Plates, of which thefollowing is a specification.

This invention relates to fastenings for safe to or vault wall components or plates, the object of the invention being to provide a somewhat` diierent form of fastening from that shown and described in my contemporaneouslypending application filed herewith, and which may be used with what is ordinarily understood to be nnmachineable metal platessuch, for instance, as manga'nese steel plates, which,as is wellknown, it is not practicable to drill or cut to form bolt-openings for the rezo ception of bolts or other forms of fastening means necessary to be inserted through holes formed by such tools, and by means of which fastening the walll components or plates will have their contiguonsf-aces or edges brought 2 5 together under high tension, thereby lobtaining a high initial resistance, which must be first overcome before such plates can be separated. I

In the drawings accompanying and forin- 3o ing a part of this specification, Figure 1 is a view of a series of -these fastening devices connecting a pair of members or plates. Fig. .2 is a cross-sectional view taken in line a o Fig. l. Fig. 3 is a 'top view of the fastening shown in Fig. '11, and Fig. 4 is a perspective view of the fastening device. l

Similar charactersof reference designate corresponding parts in the different figures of the drawings.

In practice any desired number of these improved fastenings may be used, according to the size and' character of the members or plates to be united. It will beunderstood that these fastenings may be used'to connect also dierent parts'of a safe o'r vault. In my various kinds and` formations of plates and use retaining members, which are likewise shrunk onto the projections of the plates; but these retaining members are in the form of tie-bolts. In my contemporaneously-pending application, hereinbefore -referred to, these tie-bolts in the lpreferred form thereof are shown as I-bolts. In the present instance the tie-bolts are Ushaped. This fastening comprises a plurality of projections 2 and 3, rigid oriintegral with a pair. of 'safe or vault mem- 6o bers or plates 4 and 5, to be secured together. In the form shown each plate4 i's provided with several projections 2 or 3, located at the inner side 'and adjacent to the edge thereof .and in position to register with corresponding projections carried by the other member or plate. .The projections may be of any desired shape, and instead of forming them as sepaarate and independent of each other the plates may be provided with tianges having trans- 7o verse recesses formed therein at intervals d uring' the casting of the plates for the reception of such fastening devices. The projections 2 and 3I of the plates form intermediate recesses 3,into which the legs of the tie-bolt are placed. 7 5

' To unite the projections together under sufficient tension to 'resist the opening of the joint, a retaining device is provided, which in the form shown comprises an angle member or tie-bolt 6, constructed in the preferred 8o form thereof, to coperate with several sets of projections. In the'main form shown this tis-bolt is U shaped, and when located in position each transverse portion or head 6 or 6 overlaps a pair of projections 3 of the same 85 plate, forming parts of different sets, while the arch or yoke 6"l of the bolt incloses a pair of projections constituting one set. InV this form of bolt it will be seen that theopposing portions c d of the transverse heads engage a 9o 4projection of the same set which is inclosed by the yoke of the bolt, while the relatively remote transverse portions e f engage projections of d-ierent sets. -In the organization shown the tie-bolts are alternately located,- 95

that is to say, the yoke of one bolt is' in a position reverse to that of another. Consequently two bolts will,rigidlyclamptogether three sets of projections and assist in 4clamping two other sets. Instead of forming' the loo bolt with each transverse head thereof projecting at opposite sides of its leg it could be formed without the portions c and f, Fig. 1, in which instance the b olt would simply clamp a pair of projections together. In another form thereof the portion or portionsat the right of the dotted lines b, Fig. 1, could be dispensed with, in which case one bolt would assist in clamping two sets of projections to-y gether. Of-course it will be understood that the transverse heads of the bolts may be varied in lengthas circumstances may require, and one part could be longer than another, if desired. The preferable formI of bolt, however, is a U-shaped bolt havingeach of its transverse heads projecting'in opposite directions, whereby one bolt assists in clam p 'ing three sets of projections together, and

whereby also the strain will come equally on all parts thereof, and whereby each bolt will, without assistance from any other bolt, secure or clamp two projections, while two bolts will clamp three sets of projections together under high tension. In practice these tie -vbolts, having been first heated, are inserted in the recesses between the projections and shrunk thereon,whereby the joints are formed under high pressure-that is to say, the edge faces of the plates or members are drawn together with great force and under high tensionthereby obtaining high initial resistance,which,as will be readily seen,"must be first overcome before such plates can be separated lto effect an entrance into the joint. By means of this fastening safes, vaults, and strong boxes may be made of highly-resisting material and of composite construction and which will be for all practical purposes as strong as an integral structure, since the fastening devices being shrunkon become to a certain extent integral with the projections. Then the plates are large and'heavy, it will be seen that by providing a number of these fastenings located side by side at the desired intervals iL will not be practicable to separate the plates even by the use of high explosives,.especially when such plates are formed ofv manganese steel or other unmachineable metal, since the edges ofthe plates being dra-wn together with great force, and it not beingv practicable, as is well known, to drill into plates of this character su'iciently to permit, the entrance of nitroglycerin, it is not possible in any known manner to separate the plates at the joint when connected by this improved fastening.

. Moreover, the use of this fastening avoids the necessity of im pairing the integrity of the plates for the insertion of bolts or tl'leneces-- sitybf connecting the plates by threads. The projections formed in the manner herein shown and described constitute levers, the ends of which form fulcrums, and to which levers the fastening devices are usually appliedsubstantially midway of their length,-

considering the (interfaces of the plates asa part thereof. In this way an effective means is obtained for reducing the tendency of any force applied at the outside of the plates at the joint thereof to fastening devices, and thus permit the joint to open.

For locating the projections, and thereby the members or 'plates rigid therewith, in a fixed position or alinement relative to each other, and so prevent the forcing of one plate inwardly independent of its companion plate, means cooperating with recessed walls of the projections is provided. In one form thereof this means may be independent of the tieboit, and inthis instance each of the projections is shown provided in its inner face with a recess'or slot 8, which when in communication with a similar recess or slot of a companion registering projection forms a k'eyway 9 for the reception of a key l0, by means of which the projections and thek members or plates formed as part thereof or rigid therewith maybe located in proper alinement and in fixed position relative to each other, so thatthe forcing of one inwardly independently of the other is not possible.

The term plates as used herein and in the claims is to be interpreted to include, when the fastening is used to assemble the various parts of a vault or safe or analogous structure, the front or other part of such structure, whether the same is formed as a fiat or curved plate or as a member formed of one or more parts. v
